GUN DI SCHARGING MEANS Filed Jan. 29, 1929 INVENTOR.

STATES NT FFICE DANIEL 1\T. MINK, OF FRESNO, CALIFORNIA GUN-DISCHARGING MEANS Application filed January 29, 1929. Serial No. 335,924.

My invention relates to'a device for discharging a gun, and more particularly to a gun lock adapted for automatically setting the hammer of the gun and releasing it. The

objects accomplished are as follows:

' The setting of the hammer and its release is accomplished by one pull of the trigger. A plurality of hammers can be set and released with the use of one trigger only. It

requires a complete movement back and forth of the trigger to set the hammer, to release it and to position the trigger for the next cycle of movements adapted to fire the gun. It is impossible with this device to accidentally fire two barrels at the same time, as the barrels must be fired consecutively.

The hammer will not rest on the plunger when said hammer is inactive, thus avoiding a premature firing of the gun.

- These and other objects are attained by means of the device hereinafter described and illustrated in the accompanying drawing, in which Fig. 1 shows a top plan view of my gun lock. Fig. 2 is a side view of the gun lock, partly in section. Fig. 3 shows the right hammer, the trigger and the mechanism for setting the hammer, omitting the releasing means.

39 In said drawing I have shown a portion of a gun lock 10 to which is attached trigger plate 11. Trigger plate 11 has side walls 12 and 13. The gun support is adapted to hold a gun barrel 15 in the right angle 1 1. A plunger 16 extends through the gun lock support in such position that it is aligned with the head of the hammer on one end and with the cartridge at the other end. Hammer 17 consists of an arm 18 pivoted with pivot 29 adjacent to one end thereof to the side walls 12 and 13, the end of the arm opposite the pivot having hammer head 19 thereon. The pivotal end of the hammer arm has an extension forming a dog 20 on one side thereof. On the side opposite the dog is an extension which functions as a foot 21, which foot is adapted to limit the movement of the hammer by coming in contact with trigger'plate 11. On the top of foot 21am two spring seats, the ens. nearest the hammer pivot being designated 22, and the one farthest from the pivot being designated 23. A leaf spring 24: is anchored to trigger plate 11, one end of the spring being free and p0- sitioned to normally rest on spring seat 22. This spring is preferably in the form of an elongated hook having the shorter arm of the hook engaged in notch 28 in post 27 and having the bow of the hook engaged with a member 29. The free end of the spring, being its longer end 2 1 rests normally on spring seat 22 when the hammer is at rest. The spring seat being near the pivotal means on hammer arm 18, it will exert but slight pressure on the hammer. When the hammer is drawn back, however, spring seat 23 will engage the spring and will be engaged with the spring when the hammer is about to be released, and being farther away from pivot, more power will be exerted on the hammer 7 than if the spring rest 22 were the only one provided.

For the purpose of setting the hammer and releasing it against the spring pressure, I have provided a three point cam 31 which is pivoted so it can rotate. It is here suggest ed that a cam of this kind is provided for. each hammer assembly. As cam 31 is rotated one of the projections 32 will engage the top of dog 20, pushing the dog down- 89 ward and setting the hammer. When cam 32 continues to rotate aftervthe hammer is pressed down to its lowest point of travel, cam point 32 will slide off of dog 20, thus releasing the hammer and said dog will then 3 form a stop preventing a reverse movement of the cam. For the purpose of rotating cam 31 and other cams which may be attached to the same shaft, I have provided a ratchet wheel 34 which is engaged by a pawl 35. Pawl 35 consists of a bar with a plurality of teeth therein, which teeth are adapted to engage the teeth on ratchet wheel 31. The pawl 35 is pivotally connected to trigger 36 so that by the movement of the trigger backward, pawl 35 pulls forward rotating cam 31.;

When trig er 36 is released, a spring 37 will return t e trigger to an approximately upright position, and spring 40 is adapted to hold the pawls 35 in active relation with ratchetwheel. 7

On the drawing I have shown the cam 31 engaging with the left hammer and cam 31 engaging the right hammer. These cams are positioned so that they will actuate one of the hammers alternately. Thus on one complete pull of the trigger the left hammer will be set and discharged and the cam cooperating 10 with the right hammer will be positioned for use at the next pull of the trigger.

Having described my invention, I claim: 1. Gun discharging means having a plurality of pivotally mounted hammers, separate cam means for each hammer adapted to move the hammer against a spring tension and to release said hammer at a fixed point in the rotation oi the cam, each of said hammers having a dog formed integral therewith adapted to form a stop to prevent a reverse movement of said cam, pawl and ratchet means for rotating said cams simultaneously, said pawl and ratchet means being actuated with a trigger pivotally mount ed and adapted to have a back and forth movement, said pawl and ratchet means and said cams being adapted to actuate but one hammer at one back and forth movement of the trigger. 3G 2. In a device for discharging a gun, having more than one barrel, the comoination of a plurality of hammers pivotally mounted, spring means adapted to normally draw said hammers to a fixed position, cam means for moving the hammers to a position against the spring tension and means for rotating the cam consisting of a trigger lever adapted when moved in one direction to move a pawl engaged with a ratchet wheel, which ratchet 40 wheel in turn rotates a shaft to which the said cams are attached, said cams being arranged so that on each movement bacl; and forth of the trigger lever, but one cam engages but one hammer, each of said hammers having a dog formed integral therewith adapted to cooperate with said cam and adapted to prevent a reverse movement of said cam.
